Can Helix Native update PACER LEDs when switching presets or snapshots

[Exquse]

Hi everyone,

 

I’m testing Helix Native inside Reaper 7 (Windows 11) together with a Nektar PACER and ReaLearn.
The sound is amazing, but I’m stuck on one important thing: LED sync.

 

Here’s what works:

• Block ON/OFF is assigned to automation (“Controller Assign → Bypass → Switch 01–16”).

• ReaLearn maps Helix automation → PACER LEDs.

• Clicking blocks with the mouse updates PACER LEDs correctly.

• Clicking presets with the mouse also updates the LEDs.

• Tapping Pacer toggles blocks on and off

 

Here’s what does not work:

• Selecting snapshots via MIDI CC69 (or mouse) changes the snapshot inside Helix Native,
  but no automation update is sent, so PACER LEDs don’t update.

• Selecting presets via MIDI Program Change loads the preset,
  but again no automation change is sent. (selecting presets by double click DO update the PAcer Leds)

 

So I,m lost and the core issue is:
Helix Native doesn’t seem to send any automation updates to the host when snapshots or presets are changed via MIDI.

 

My question:

 Is it possible to keep a hardware controller (like the PACER) in sync when changing Helix Native presets/snapshots via MIDI?
Does Helix Native send any automation to the host when doing this?

 

If anyone has a working setup or a known workaround, I’d really appreciate it.

 

Thanks en best regards,

Automation is something I never use, but if REAPER can activate/deactivate an LED on an external controller, then it must be sending a signal of some sort.

What signal is being sent?

Finding out what message is being sent in the operations that work is the first step.

Thank you for youre reply. Its solved. It seems there is a snapshot function in Realearn. With that I control the blocks in Helix and the leds on the floorboard
